我试图检测用户何时触摸了网页内的链接,而不是触摸页面的任何其他部分,但它不工作 - 会发生什么是在下面的代码无论我接触到哪个链接,都会弹出“触及非链接”的提醒。检测用户何时触摸链接
这段代码有什么问题?
function addListeners()
{
alert('adding listeners');
// Attach the listener for touches on non-links to the document node
document.addEventListener("touchstart", touchesOnNonLinksListerner, false);
// Attach the listener for touches on links to the anchor nodes
var links = document.getElementsByTagName("a");
for (var index = 0; index < links.length; ++index)
{
links[index].addEventListener("touchstart", touchesOnNonLinksListerner, false);
}
};
function touchesOnNonLinksListerner(event)
// Catches touches anywhere in the document
{
alert("touched a non link");
}
function touchesOnLinksListener(event)
// Listens for touches which occur on links, then prevents those touch events from bubbling up to trigger the touchesOnNonLinksListerner
{
alert("touched a link");
if (typeof event == "undefined")
{
event = window.event;
}
event.stopPropegation();
}
拼写错误'stopPropagation()'。 – JJJ 2012-03-10 16:04:14
如果这里的帖子中没有输入错误,那应该是event.stopPropagation() - ..pa .. not ..pe .. – 2012-03-10 16:05:31
也有几个地方拼错了'Listener'。 – 2012-03-11 01:04:39
